What I claim is:

l. In an internal combustion engine, a

'cylindrical valve easing, a rotary valve inouiited in said easing having ay pluralityv of longitudinal grooves, and annular groovee of greater depth than the longitudinal grooves intersecting the latter 'intern'iediate their ends, packing strips arranged in the and split expanding rings arrangedin the annular grooves nornially retaining the packing strips in Outwardly extended position.

pinion@ i 1n an interna-l eombustion engine, a

,cylindrical iialif'e'veasing, a rotary valve arranged in. the niet-mentioned annular grooves, packing stripe arranged in the'longitudinal grooves, and slit expanding rings arranged in the ser:ond -nienti.oned annu!` lar groove normally retaining the packing strips in outwardly extended poeition' against the wall of the bore of eaideasing In testimony whereof l affix inyosiginiture in present-.e -oif two w'tnesses,
